The continuation of current trends in shrub and tree expansion could further amplify this atmospheric heating by two to seven times.

Another principal investigator for the project, Laura Pan, senior scientist at the National Center for Atmospheric Research in Boulder, Colo., believes storm clusters over this area of the Pacific are likely to influence climate in new ways, especially as the warm ocean temperatures (which feed the storms and chimney) continue to heat up and atmospheric patterns continue to evolve.

Sulphur particles in the stratosphere reflect sunlight and therefore act antagonistically to atmospheric greenhouse gases like CO2, which capture the heat of the sun on Earth.

But it is a complicated picture: the effect that extra atmospheric CO2 has in these kind of experimental setups might not reflect its effects in the real world, where other factors — such as elevated heat, or changes in precipitation — come into play.

This is due to the unabated upward trends in human population growth (6), atmospheric heat content, and OA (2).

In the North Atlantic, more heat has been retained at deep levels as a result of changes to both the ocean and atmospheric circulations, which have led to the winter atmosphere extracting less heat from the ocean.
